Carrier-free /sup 54/Mn was uniformly mixed into individual pots of three different soils. The soils were Yolo loam (slightly acid), Hacienda loam (calcareous), Dinuba fine sandy loam (neutral). Phaseolus vulgaris var. Improved Tendergree (bush bean) and Zea mays var. Golden Cross bantum (corn) were grown in the soils with the presence and absence of various chelating agents. Yields and total Mn and /sup 54/Mn were determined in the leaves and specific activities were calculated. After cropping, the control soils were assayed for water soluble, exhangeable, easily reducible, and 10/sup -3/M EDDHA, EDTA, DTPA, and NTA soluble /sup 54/Mn and Mn. Bush bean leaves contained more /sup 54/Mn and Mn per plant than did corn and the content of each decreased with increasing pH of the three soils used. The specific activities of the Mn in bush bean leaves were similar to those for the easily reducible Mn for the three different soils but the specific activities in the corn, in contrast, were more nearly like those in the exchangeable Mn in the soils.
